The seven chapters in this volume cover twenty days. Chapters I–VI continue — from August 15 to August 31 — the record of the efforts made by His Majesty's Government to deter Germany from aggression against Poland. These efforts failed. The last chapter of the volume describes the diplomatic steps taken by His Majesty's Government on September 1, 2, and 3, and ends with the British declaration of war on Germany. The documents in this chapter include exchanges with the French Government on the times of delivery and expiry of an ultimatum to Germany, and exchanges with the Italian Government on the proposals of the latter for an international conference.
